 1,  Technical Data 

1, Product  Description 

Sunray series high pressure preheated solar water heater with copper coil is a kind of thermosiphon solar water heater with pressurized hot water using. A pile of heat exchanging copper coil is installed in the hot water storage tank with two connections as inlet andoutlet, pressure cold water goes through copper coil and all the way it absorbs heat from hot water in storage tank, in this way at copper coil outlet we get instant pressure hot water continuously.

Assistant Tank

with a ball valve inside automatically control water refill into storage tank and keep it full always;

Heat Exchanger 

Usually a pile of copper pipe coil is fixed inside storage tank for fast heat exchange, as a substitute, 

lower coststainless pipe coil is also available, in some cases a small pressure tank is adopted as heat exchanger inside storage tank.

3  Advantages                                                                     

Comparing with non-pressure glass tube solar water heater

1. Heat exchanger connecting with city water directly to get high pressure hot water;

2. Hot water from heat exchanger is instant and clean;

3. No need to install heater on roof top for pressure hot water outlet;

Comparing with heat pipe solar water heater

1. More lower cost;

2. More simple structure and installation;

Comparing with Pre-heat flat plate solar water heater:

1. Higher efficiency collector, much lower heat loss;

2. Super anti-freezing performance for cold weather;

3. Convenience in parts carrying and installation;
